MAX16046/MAX16048
12-Channel/8-Channel EEPROM-Programmable
System Managers with Nonvolatile Fault Registers
Acknowledge
The acknowledge bit (ACK) is the 9th bit attached to
any 8-bit data word. The receiving device always gen-
erates an ACK. The MAX16046/MAX16048 generate an
ACK when receiving an address or data by pulling SDA
low during the 9th clock period (Figure 11). When
transmitting data, such as when the master device
reads data back from the MAX16046/MAX16048, the
device waits for the master device to generate an ACK.
Monitoring ACK allows for detection of unsuccessful
Slave Address
Use the slave address input, A0, to allow multiple identi-
cal devices to share the same serial bus. Connect A0 to
GND, DBP (or an external supply voltage greater than
2V), SCL, or SDA to set the device address on the bus.
See Table 31 for a listing of all possible 7-bit addresses.

Address
data transfers. An unsuccessful data transfer occurs if
the receiving device is busy or if a system fault has
occurred. In the event of an unsuccessful data transfer,
the bus master should reattempt communication at a
later time. The MAX16046/MAX16048 generate a NACK
after the command byte received during a software
reboot, while writing to the EEPROM, or when receiving
